Invalid format: isGranted not found

Error message

Invalid format: isGranted not found

What it means

PermissionRule's constructor reads the isGranted boolean (and optionally flags) from the flattened rule string. If the isGranted token is absent, it throws this IllegalArgumentException; note that a missing flags token is tolerated for backward compatibility, but isGranted is mandatory.

Solutions

  1. Add the "true"/"false" isGranted token after the permission name in the rule string
  2. Validate that at least one token remains before constructing PermissionRule
  3. Re-export rules with the current AppManager version
  4. Catch IllegalArgumentException per-line during import and skip bad entries

Example fix

// before
new PermissionRule(pkg, "android.permission.CAMERA", new StringTokenizer("com.example\tandroid.permission.CAMERA")); // throws
// after
new PermissionRule(pkg, "android.permission.CAMERA", new StringTokenizer("com.example\tandroid.permission.CAMERA\ttrue\t0"));
Defensive patterns

Strategy: validation

Validate before calling

String[] p = line.split("\t");
if (p.length < 3) throw new IllegalArgumentException("PERMISSION rule needs isGranted (flags optional)");
Boolean.parseBoolean(p[2]);

Type guard

boolean isParsablePermissionRule(String line) { String[] p = line.split("\t"); return p.length >= 3 && (p[2].equals("true") || p[2].equals("false")) && (p.length < 4 || p[3].matches("\\d+")); }

Try / catch

try { new PermissionRule(pkg, perm, tokenizer); } catch (IllegalArgumentException e) { importer.report(line, e); }

Prevention

When it happens

Trigger: new PermissionRule(packageName, permName, tokenizer) invoked when the tokenizer has no token left after the permission name, i.e. the flattened PERMISSION rule line ends right after the permission.

Common situations: Old or hand-edited rules files lacking the isGranted field, truncated imports, or delimiter mistakes dropping the boolean token (while the missing trailing flags would have been fine).
